Answer:
Hi Emily
Step-by-step explanation:
Domain is the inputs or the x values, interval notation it's [ -7, 1] it looks like a point but it's not, it's a range, use the square brackets for including the numbers in the interval and the round brackets for excluding the numbers shown
Range is the outputs or y values [-4, 0]
so if this is a function, then any input will give one and only one out put, which this function does do that so it is a function. :) if you're wondering about some of the outputs being the same that's okay. it's the inputs that have to be only one. in other words a straight line is all the values of x that equal one value of y .. like x=4... that's a straight line at y of 4 see?
